A small piece of vitamin C seems to be a panacea for all diseases. Is vitamin C really that magical? In fact, vitamin C mainly exists in organisms and is produced through metabolism, but there are many exceptions.
The Scientific Knowledge of Nutritional Supplement published by China Nutrition Society pointed out the role of vitamin C. Vitamin C supplementation is helpful to reduce uric acid levels in patients with hyperuricemia, fasting blood glucose and glycosylated hemoglobin levels in patients with type 2 diabetes, and improve vascular endothelial function in different populations. But generally speaking, healthy adults don't need to deliberately supplement vitamin C. They recommend a balanced diet. If there is a serious partial eclipse or malnutrition, they need appropriate supplements.
1, eat in moderation
When taking vitamin C, we must pay attention to controlling the intake. Although the toxicity of vitamin C is relatively low, if we take too much vitamin C, such as taking more than 3000 mg of vitamin C every day, it will lead to some adverse reactions. Including diarrhea, gastrointestinal diseases, uric acid excretion will be affected to some extent, which will have an impact on health. Therefore, we must pay attention to controlling the dosage and using drugs reasonably according to the doctor's advice in order to better maintain our health.
2. Don't use it for a long time
If you take vitamin C for a long time, it will easily lead to the formation of stones, because vitamin C is mainly produced by eating fruits, vegetables and other foods. However, if you take vitamin C tablets directly, it will lead to the formation of stones, which is not good for your health. In addition, taking vitamin C tablets for a long time will also increase the risk of deep vein thrombosis.
Don't eat on an empty stomach.
Never take vitamin C if you have peptic ulcer recently. Taking vitamin C at this time is easy to stimulate ulcers, leading to deterioration of the condition and even gastric bleeding. In addition, we must be careful not to eat vitamin C on an empty stomach, otherwise it will easily stimulate the stomach.
According to the survey, taking a large number of vitamin C tablets for a long time is also easy to reduce the body's resistance, and it will also have side effects when treating some diseases. People take a certain amount of vitamin C tablets every day, no more than two. If there are more than two tablets, it is likely to have great side effects.
1, reducing immunity
As we all know, vitamin C supplementation can enhance physical fitness and improve immunity. However, taking too much vitamin C every day will lead to too many vitamins in the body, which will have a negative impact on the body, reduce our immunity and have a negative impact on health.
2, leading to the emergence of diarrhea.
Because vitamin C is acidic, excessive intake will excessively stimulate gastric acid secretion, leading to gastric acid reflux. For people suffering from or prone to gastric ulcer and gastroesophageal reflux, 100~200mg vitamin c can be taken generally, but it is definitely not suitable for taking in large doses, otherwise it will stimulate excessive gastric acid secretion, leading to stomach discomfort, excessive intestinal peristalsis and diarrhea.
3. Osteoporosis is more serious
Taking too much vitamin C for a long time may lead to some sequelae in patients with osteoporosis. Theoretically speaking, osteoporosis patients need to supplement more calcium, but if they supplement high doses of vitamin C for a long time at the same time, they will synthesize "calcium oxalate", completely losing the purpose of eating calcium to supplement bone calcium. In addition, the original calcium will be continuously lost, and the problem of osteoporosis will only become more and more difficult.
4. Stone appears
Excessive intake of vitamin C will not only cause rash allergy in clinic, but also produce oxalic acid as a metabolite in the body. Excessive intake will increase the amount of oxalic acid. If combined with calcium in the body, a large amount of calcium oxalate will be formed, which is equivalent to creating the best opportunity for stones. Especially prone to urinary calculi or kidney calculi. Therefore, the risk of stones will be much higher than that of ordinary people if too many large doses of vitamin C are not supplemented properly.
Although vitamin C is an essential nutrient for human body, if it is taken in excess, it will inevitably have a serious impact on human body. Any substance, including excessive fat input, can also lead to obesity and cardiovascular disease. Whether it is food intake or nutritional supplement, we should learn to supplement it properly, which is of great benefit to our health.
